1 Mycologia Iranica 1(2): 65 74, 2014 Original Article Additions and corrections to names published in Cercospora in Iran M. Pirnia Department of Plant Protection, Faculty of Agriculture, University of Zabol, Zabol, Iran Abstract: In this paper, the taxonomy of some previously reported taxa as Cercospora apii s. lat. in Iran is discussed and some new records are listed. Cercospora species on Abelia grandiflora (C. deutziae), Erythrina crista-galli (C. erythrinicola), Euphorbia heterophylla (C. pulcherrimae) and Zanthedeschia aethiopica (C. richardiicola) are new for mycobiota of Iran. Cercospora iridis which has been previously reported from Iran probably belongs to the genus Passalora, but more specimens should be examined for final conclusion. Key words: Taxonomy, anamorphic fungus, leaf spotting pathogen, new record INTRODUCTION Cercospora Fresen. is one of the largest genera among cercosporoid fungi and its species are associated with leaf spots and considered as important pathogens on various host plants. (Crous & Braun 2003). Chupp (1954), who adopted a broad generic concept listed over 1800 species. By careful morphological examination of Cercospora and similar taxa, Deighton (1973, 1976) segregated and introduced new genera. Crous & Braun (2003) published an annotated list of Cercospora and Passalora names with more than 5700 taxa. Recently, Ershad (2009) corrected 59 names in Cercospora previously published from Iran, but he did not follow to synonymize morphologically indistinguishable taxa in Cercospora apii s. lat. Study on Cercospora and allied genera is more considered in recent years in Iran. Pirnia et al. (2012 a, b, c, d) identified new species of cercosporoids from the north of Iran. Hesami et al. (2011, 2012) introduced new Cercospora and Cercospora-like species from Guilan province. Recently, Bicharanlou et al (2013 a, b, c) and Behrooz et al. (2015) reported new cercosporoid species from Mazandaran and Kohgiluyeh and Boyer-Ahmad Provinces, respectively. MATERIALS AND METHODS Specimens from the north of Iran (Guilan, Mazandaran, Golestan and Ardabil provinces) and all specimens belonging to Cercospora deposited in fungal reference collection of Ministry of Jihad-e- Agriculture IRAN in Iranian Research Institute of Plant Protection were morphologically re-examined. Microscopic slides were prepared from stromata, conidiophores and conidia in 25% lactic acid. Characters such as pigmentation, shape and dimension of conidia and conidiophores and thickness and darkness of conidial scars and hila were studied. Drawings were made using a drawing-tube attached to an Olympus BH2 microscope. RESULTS AND DISCUSSION According to Crous & Braun (2003), some taxa in the genus Cercospora on various host plants are morphologically indistinguishable. Therefore, they proposed Cercospora apii s. lat. for those taxa and linked 83 host genera to the latter species. Pirnia et al. (2010) and Bicharanlou et al. (2013a) followed Crous & Braun (2003) and linked 19 hosts with C. apii s. lat. based on Braun's idea this proposal is a temporary solution for Cercospora apii species complex and new molecular evidences are needed to confirm it, therefore previous valid names are acceptable as separate species. In this research, the taxa which previously placed in Cercospora apii s. lat. were re-examined and segregated on various hosts based on morphological characters. Cercospora species on Abelia grandiflora L. (C. deutziae Ellis & Everh.), Erythrina crista-galli L. (C. erythrinicola Tharp), Euphorbia heterophylla L. (C. pulcherrimae Tharp) and Zanthedeschia aethiopica (L.) Spreng. (C. richardiicola G.F. Atk.) are new records for mycobiota of Iran. Cercospora althaeina Sacc. (on Gossypium hirsutum Cav.), C. avicennae Chupp (on Abutioln theophrasti Medic.), C. beticola Sacc. (on Beta vulgaris L.), C. bizzozeriana Sacc. & Berl. (on Cardaria draba (L.) Desv.), C. brunkii Ellis & Galloway (on Pelargonium zonale (L.) L Her. ex Ait), C. canescens Ellis & G. Martin (on Vigna sinensis (L.) Endl.), C. caricis Oudem. (on Carex orbicularis Boott.), C. gerberae Chupp & Viegas (on Gerbera jamesonii Hook), C. hydrangeae Ellis & Everh. (on Hydrangea macrophylla (Thunb.) Ser.), Submitted 18 January 2014, accepted for Publication 1 June 2014 Corresponding Author: pirnia@uoz.ac.ir 2014, Published by the Iranian Mycological Society

2 66 Mycologia Iranica - Vol. 1, 2014 C. lactucae-sativae Sawada (on Lactuca serriola L.), C. peckiana Chupp (on Rumex crispus L., R. sanguineus L.), C. physalidis Ellis (on Lycopersicon esculentum Mill.), C. sonchi Chupp (on Sonchus arvensis L.), C. zebrina Pass. (on Medicago sp.) and C. zonata G. Winter (on Vicia faba L.) were identified on the specimens collected from the northern provinces of Iran. Other morphologically similar Cercospora species listed by Ershad (2009) on Gerbera jamesonii (C. gerberae), Glycine max L. (C. kikuchii T. Matsumoto & Tomoy.), Hibiscus esculentus L. (C. malayensis Stev. & Solh.), Hydrangea hortensia L. (C. hydrangeae), Impatiens balsamina L. (C. fukushiana (Mat.) Yam.), Medicago sp. (C. medicaginis Ellis & Everh.), Petunia hybrida Wilm. (C. physalidis Ellis) and Vigna sinensis (C. canescens) proved to be the correct names according to morphological descriptions provided in Chupp (1954). Cercospora iridis which was previously reported from Iran (Pirnia et al. 2010), probably belongs to the genus Passalora, but the amount of the specimen was not sufficient for the exact identification. All specimens are deposited in IRAN. Key to Cercospora species reported from Iran 1.

Mycol. 4: 5 (1888) Leaf spots circular, center greyish-white, mm in diameter; stromata lacking or composed of a few brown cells, µm wide; caespituli epiphyllous; conidiophores in small fascicles, medium dark brown, uniform in color, not branched, septate, µm; conidial scars conspicuous, thickened and darkened, terminal and lateral; conidia hyaline, acicular to cylindrical, multiseptate, base truncate, tip subobtuse, µm; hilum thickened and darkened (Fig. 1). Specimen examined: IRAN, Mazandaran Province, Nowshahr, on Abelia grandiflora, 29 Oct. 2012, B. Bicharanlou (IRAN F). C. apii by Bicharanlou et al. (2013b). Morphology of the specimen examined agrees with description of C. deutziae provided by Chupp (1954). The species is distinguished from C. apii s. lat. by having moderately shorter conidiophores and conidia. Fig. 1. Cercospora deutziae on Abelia grandiflora.

4 68 Mycologia Iranica - Vol. 1, 2014 Cercospora erythrinicola Tharp, Mycologia 9: 109 (1917) Leaf spots circular to subcircular, greyish white, 1 3 mm in diameter; stromata lacking or composed of a few brown cells, µm wide; caespituli amphigenous, mostly epiphyllous; conidiophores pale brown, paler and narrower towards the tip, not branched, septate, µm; conidial scars conspicuous, thickened and darkened, terminal and lateral; conidia hyaline, acicular, straight to curved, multiseptate, base truncate, tip acute to subacute, µm; hilum thickened and darkened (Fig. 2). Specimens examined: IRAN, Mazandaran Province, Nowshahr, on Erythrina crista-galli, 9 Oct , B. Bicharanlou (IRAN F). Note: Specimen on above mentioned host was previously reported as C. apii by Bicharanlou et al. (2013b). In this species, fascicles were moderately dense and some conidiophores were sparingly sinuous to 1-3 geniculate and conidia were moderately shorter than 150 µm. These characters distinguish the species from C. apii s. lat. and fit well with description of C. erythrinicola in Chupp (1954). Cercospora pulcherrimae Tharp, Mycologia 9: 114 (1917) Leaf spots circular to subcircular, 1 3 mm in diameter; stromata composed of a few brown cells, µm wide; caespituli amphigenous, mostly epiphyllous; conidiophores olivaceous brown, paler and narrower towards the tip, not branched, septate, µm; conidial scars conspicuous, thickened and darkened, terminal and lateral; conidia hyaline, acicular, straight to curved, multiseptate, base truncate, tip subacute, µm; hilum thickened and darkened (Fig. 3). Specimens examined: IRAN, Golestan Province, Gorgan, on Euphorbia heterophylla, 10 Nov. 2010, M. Pirnia & R. Zare (IRAN F). C. apii by Pirnia et al. (2010). Moderately short conidiophores and conidia separate the species from C. apii s. lat., and hyaline acicular conidia separate C. pulcherrimae from the others on Euphorbia (Chupp 1954). Fig. 2. Cercospora erythrinicola on Erythrina crista-galli. (A) Conidiophores, (B) Conidia, (C) Symptoms on leaf, scale bar = 50 µm.

Cercospora richardiicola G. F. Atk. (richardiaecola), J. Elisha Mitchell Sci. Soc. 8: 51. (1892) Leaf spots circular to subcircular, center greyish white, with narrow dark brown margin, 1 12 mm. in diameter; stromata present, small to moderately developed, µm wide, brown; caespituli amphigenous, mostly hypophyllous, punctiform, conidiophores in small fascicles, arising from stromata, pale to olivaceous brown, paler towards the tip, erect, geniculate to sinuous in the upper part, not branched, µm, septate; conidiogenous cells integrated, terminal; conidial scars conspicuous, thickened and darkened, terminal and lateral; conidia hyaline, acicular, straight to curve, multiseptate, 8 12 transverse septa, (2.5-)3 4 µm, base truncate, tip acute; hilum thickened and darkened (Fig. 4). Specimen examined: IRAN, Guilan Province, Some'e-Sara, on Zanthedeschia aethiopica, 15 July. 2007, A. Khodaparast (IRAN F). C. apii by Pirnia et al. (2010). Morphology of the specimen agrees with the description of C. richardiaecola given by Chupp (1954). The species was originally published as C. richardiaecola, which is corrected to C. richardiicola in this study, according to Crous & Braun (2003). The species is somehow morphologically close to C. callae, but the latter species can be distinguished by its obclavate, shorter and wider conidia. Cercospora bizzozeriana Sacc. & Berl., Malpighia 2: 248. (1888) Specimens examined: IRAN, Yazd Province, Taft, on Cardaria draba, 8 May Khorramnejad (IRAN F); Northern-Khorasan province, Shirvan, 3 July B. Bicharanlou (IRAN F). Note: The species is characterized by having obclavate to cylindrical conidia and moderately short conidiophores, which was listed by Pirnia et al. (2012a) for the first time from Iran. Cercospora caricis Oudem., Nederl. Kruidk. Arch. II, 6: 59. (1892) Specimen examined: IRAN, Ardabil Province, Neur Lake, on Carex orbicularis, 22 May Javadi-Estahbanati (IRAN F). Note: Chupp (1954) introduced Cercospora caricis on various species of the genus Carex. The species is characterized by having short conidiophores and acicular to cylindro-obclavate conidia, and was listed by Pirnia et al. (2012a) for the first time from Iran.

Cercospora peckiana Chupp, A monograph of the fungus genus Cercospora: 449 (1954) Specimens examined: IRAN, Golestan Province, Gorgan (Jahan Abad village), on Rumex sanguineus, 13 May M. Pirnia (IRAN F); Golestan Province, Gorgan, on Rumex crispus, 10 May M. Pirnia (IRAN F); Golestan Province, Gorgan, Tuskestan Forest, 9 Nov M. Pirnia & R. Zare (IRAN F). Note: The species is morphologically similar to Cercospora apii, but differs by moderately short conidiophores and conidia as well as obclavatecylindrical conidia and was listed by Pirnia et al. (2012a) for the first time from Iran. Cercospora althaeina Sacc., Michelia 1: 296. (1878) Specimen examined: IRAN, Golestan Province, Gorgan, on Gossypium hirsutum, Date unknown, Mirsalavatian (IRAN 4650 F). Note: Ramularia areola was previously reported from the same specimen in Iran (Ershad 2009). Careful examination of the specimen showed that some leaves were infected by Cercospora althaeina, which was previously reported on Althaea rosea Cav. in Iran. Cercospora avicennae Chupp, A monograph of the fungus genus Cercospora: 369 (1954) Specimen examined: IRAN, Golestan Province, Shastkola forest, on Abutilon theophrasti, 8 Nov. 2010, M. Pirnia & R. Zare (IRAN F). C. apii by Pirnia et al. (2010). Morphological characteristics of the specimen examined agree well with description of C. avicennae in Chupp (1954). Cercospora beticola Sacc., Nuovo Giorn. Bot. Ital. 8: 189. (1876) Specimens examined: IRAN, Golestan Province, Gorgan, on Beta vulgaris, 13 May 2011, M.

Scharif (IRAN 439 F); Fars Province, Kazerun, 13 May 1969, Ahmadinejad (IRAN 440 F); North- Khorasan Province, Bojnurd, 16 Nov , Ahmadinejad (IRAN 441 F); Khuzestan Province, Ahvaz, date unknown, E. Esfandiari (IRAN 442 F); Golestan Province, Gorgan, 20 Apr. 1947, Mirsalavatian (IRAN 443 F); Guilan Province, Rasht, 3 Aug. 1947, E. Esfandiari (IRAN 444 F); Khuzestan Province, Ahvaz, on Beta maritime L., 9 Feb. 1971, Ebrahimi (IRAN 433 F). Note: According to Chupp (1954), C. beticola is characterized by moderately short conidiophores. Crous & Braun (2003) synonymized C. beticola under C. apii s. lat., but Groenewald et al. (2006) showed that both C. apii and C. beticola had wider host ranges and represented distinct species. Iranian specimens are classified under C. beticola, but it is probable that some specimens in Iran are infected by C. apii s. lat. Cercospora brunkii Ellis & Galoway, J. Mycol. 6: 33. (1890) Specimens examined: IRAN, Guilan Province, Sume'e Sara, on Pelargonium zonale, 25 June 2010, M. Pirnia (IRAN F); Mazandaran Province, Mahmoudabad, 16 Aug. 2012, B. Bicharanlou (IRAN F). Note: Specimens from Guilan and Mazandaran provinces were previously reported as C. apii by Pirnia et al. (2010) and Bicharanlou et al. (2013b). C. brunkii is a common name on Pelargonium and Geranium (Geraniaceae). The species is characterized by having moderately shorter conidiophores and short acicular to obclavate conidia. Cercospora canescens Fresen., Beitr. Mycol. 3: 91 (1863) Specimens examined: IRAN, Guilan Province, Rasht, on Vigna sinensis, 25 July 2010, M. Pirnia (IRAN F); Guilan Province, Astaneh- Ashrafieh, 24 June 2010, M. Pirnia (IRAN F); Guilan Province, Sume'e Sara, 25 June 2010, M. Pirnia (IRAN F); Mazandaran Province, Babol, 12 Sept. 2010, M.A. Aghajani (IRAN F), Guilan Province, Rasht, 28 Aug. 1974, Gh. Scharif (IRAN 454 F). Note: Specimens on above mentioned host from Guilan province were previously reported as C. apii by Pirnia et al. (2010). There are three Cercospora species on Vigna spp., which are morphologically distinguishable from each other, including C. canescens (Pale brown conidiophores and long acicular conidia), C. kikuchii T. Matsumoto & Tomoy. (Darker colored conidiophores in dense fascicles and shorter conidia) and C. longispora Peck. (Pale olivaceous brown conidiophores and colored conidia). Cercospora gerberae Chupp & Viegas, Bol. Soc. Brasil. Agron. 8: 27. (1945) Specimens examined: IRAN, Mazandaran Province, Mahmoudabad, on Gerbera jamesonii, 29 Sept. 2012, B. Bicharanlou (IRAN F); Mazandaran Province, close to Motel Ghou, 3 Oct (IRAN 468 F). Note: The specimen from Mahmoudabad was previously reported as C. apii by Bicharanlou et al. (2013b), but moderately shorter conidiophores and conidia separate C. gerberae from C. apii s. lat. Morphology of the specimen examined fit well with description of C. gerberae in Chupp (1954). Cercospora hydrangeae Ellis & Everh., J. Elisha Mitchell Sci. Soc. 8: 52. (1892) Specimen examined: IRAN, Mazandaran Province, Nowshahr, on Hydrangea macrophylla, 14 July B. Bicharanlou (IRAN F). C. apii by Bicharanlou et al. (2013b). Morphology of the specimen examined is identical with description of C. hydrangeae in Chupp (1954). Two species of Cercospora, including C. hydrangea and C. yakushimensis Togashi & Katsuki are reported on Hydrangea. The latter species is distinguishable by having shorter conidiophores and conidia. Cercospora iridis Chupp, A monograph of the fungus genus Cercospora: 260 (1954) Specimen examined: IRAN, Guilan Province, Bandar Anzali, on Iris sp., 25 June 2010, M. Pirnia (IRAN F) Note: Studying a specimen on Iris sp., Pirnia et al introduced Cercospora iridis with short cylindro-obclavate conidia and small conidiophores. Careful microscopic examination showed that fungal structures and conidiogenous loci were very close to the genus Passalora. Unfortunately, the amount of the specimen was not sufficient for the exact identification, and more specimens need to be investigated. Cercospora lactucae-sativae Sawada, Rep. Gov. Agric. Res. Inst. Taiwan 35: 111 (1928) Specimens examined: Iran, Mazandaran Province, Sari, on Lactuca serriola, 12 May 2011, M. Pirnia (IRAN F); Northern-Khorasan Province, Shirvan, 3 July 2011, B. Bicharanlou (IRAN F).

8 72 Mycologia Iranica - Vol. 1, 2014 Note: Cercospora lactucae-sativae was previously reported on Lactuca sativa L. (Pirnia et al. 2010). Old collections from Iran are published as Cercospora longissima Cugini ex Sacc., but Crous & Braun (2003) replaced C. longissima by C. lactucae-sativae as its synonym. Cercospora medicaginis Ellis & Everh., Proc. Acad. Nat. Sci. Philadelphia 43: 91. (1891) Specimen examined: IRAN, Ahoudasht, on Medicago sp. 10 Mar. 1948, E Esfandiari (IRAN 469 F). Note: Conidiophores were pale olivaceous brown, paler and narrower towards the tip. Average range of conidiophores and conidial size was more than C. zebrina on Medicago in this research. Cercospora physalidis Ellis Amer. Naturalist 16: 810 (1882) Specimens examined: Iran, Guilan Province, Astaneh-Ashrafieh, on Lycopersicon esculentum, 24 June 2010, M. Pirnia (IRAN F); Guilan Province, on Petunia hybrida, 23 Aug. 1973, Akhavizadegan (IRAN 475 F). Note: Specimen on Lycopersicon esculentum was previously reported as C. apii by Pirnia et al. (2010). C. physalidis is a common species on various genera of Solanaceae (Crous & Braun 2003). Morphological characteristics of the two examined specimens agree with description of C. physalidis represented by Chupp (1954). Cercospora sonchi Chupp, A monograph of the fungus genus Cercospora: 159 (1954) Specimen examined: IRAN, Mazandaran province, Sari, on Sonchus arvensis, 19 Nov. 2012, B. Bicharanlou (IRAN F). C. apii by Bicharanlou et al. (2013b). C. sonchi was previously reported by Hesami et al. (2012) on Taraxacum officinalis in Iran, but this is the first report of the species on Sonchus arvensis. Cercospora zebrina Pass., Hedwigia 16: 124. (1877) Specimen examined: IRAN, Lorestan Province, Khorram-Abad, on Medicago sp., 14 April 2010, Naemifar (IRAN F). Note: C. zebrina is a common species on Trifolium spp., but has been also found on Medicago spp. The species is characterized by having short pale to medium dark olivaceous brown conidiophores which are uniform in color and moderately short acicular conidia. Cercospora zonata G. Winter, Hedwigia 23: 191 (1884) Specimens examined: IRAN, Golestan Province, Gorgan, on Vicia faba L., 13 May 2011, M. Pirnia (IRAN F); Khuzestan Province, Ahvaz, Hamidieh, 24 Mar. 1948, E. Esfandiari (IRAN 466 F); Mazandaran Province, Babol, Hamzeh-Cola, 12 Feb. 1983, Torabi (IRAN 467 F). Note: The species is characterized by having moderately wide and short conidiophores with wide obclavate to cylindrical conidia.
